Dunbar - Not just for line trainers either. I find that probably 90% of all safety-critical errors (or crashes) I see in the simulator can be traced back neatly to one of the NOTECHS categories: cooperation, leadership & management, decision-making or situational awareness. I continually find myself going back to NOTECHS to debrief these effors.
Fortunately, the majority of us on this thread at least have the luxury of some level of company SOPs, and crew who are trained and constituted to work together as a team. It is quite scary to find myself training so many crews from around the world who are out there flying every day, who have no SOPs, and little concept of MCC! Although I do my best with the crews I see to sow the seeds of CRM,
I am continually updating my list of "operators never to fly with as a passenger"!!!
